x = number of 5 dollar notes
\n" ); document.write( "y = number of 10 dollar notes
\n" ); document.write( "---
\n" ); document.write( "x + y = 90
\n" ); document.write( "5x + 10y = 500
\n" ); document.write( "---
\n" ); document.write( "put the system of linear equations into standard form
\n" ); document.write( "---
\n" ); document.write( "x + y = 90
\n" ); document.write( "5x + 10y = 500
\n" ); document.write( "---
